Tar – single-column continuous distillation: two-stage anthracene oil reflux rate, light oil reflux rate from the fractionation column
Thread Content
I would like to ask fellow sailors: what are the flow rates of anthracene oil returning from the single-column continuous distillation process, and those of light oil returning from the fractionation tower?
15% and 35% of anhydrous tar, respectively
The reflux rate is generally determined by the temperature at the top of the tower, and the product quality influences the control of that temperature at the top of the tower
The reflux rate is determined by the temperature at the top of the tower; generally, the reflux rate for anthracene oil is around 10% of the amount of tar processed. (In some cold regions, no reflux is used unless dealing with diphenylanthracene oil.) The reflux rate for light oil is usually around 50% of the amount of tar processed. Some tar types require a larger amount of reflux due to their composition; if there are few light components in the raw material, the light oil will be depleted in a short time. (Within 8-20 hours)
I’m not sure about the source of the data provided by the friend upstairs. In general, when carrying out process design, 15% and 35% of anhydrous tar are used as references for the design of equipment and process pipelines. This post was last edited by I don’t understand on 2009-4-2 at 22:04
But the key is the components of the raw material tar
